a) Connect a positive conclusion of the rechargeable battery to a conclusion of "h", and a negative conclusion of the rechargeable battery to a conclusion of "e".

b) Check that tension between conclusions of "b" and "e" will change from 0 in up to the tension of the rechargeable battery, at connection of a positive conclusion of the rechargeable battery with a conclusion of "g".

If result of check not satisfactory, replace the relay.

c) Connect a positive conclusion of the rechargeable battery to a conclusion "with".

d) Check that tension between conclusions of "b" and "e" changes, is as shown lower in the drawing, at disconnection of a positive conclusion of the rechargeable battery from a conclusion "with".

If result of check not satisfactory, replace the relay.
